Charge a Thinkpad T580 (USB-C) from 12V DC?

Hi,

 

just got my new T580 and I would like to charge it dom 12V DC.

T580 power connector is USB-C, and I can't find any stock charger for 12V.

I did google a "Puro Power Delivery Type-C", which has 30W. Is that enough for the T580?

 

Thanks for any help!

Re: Charge a Thinkpad T580 (USB-C) from 12V DC?

Welcome to the forum.

 

USB-C comes in many variants. One is Power Delivery (PD). USB-C Compatibility (including Power Delivery)

 

However even within PD there are variants to the standard that supply different voltages and different currents. In the case of the T580 the USB-C PD variant must be able to supply several voltages between 5VDC and 20VDC. The Puro Power Delivery Type-C Fast Car Charger - 30W - Black (if that is what you refer to) doesn't supply 20VDC so it won't work.

 

The T580 range comes with AC chargers that supply either 45W or 65W depending on the model. That too means that a 30W charger, even if it did deliver the appropriate voltages, would not be powerful enough for a T580.

 

Something like this High Power USB-C Car Charger appears to be able to power a T580. The specs say "USB-C Output (DC): 20V/3A, 15V/3A, 12V/3A, 9V/3A, 5V/3A." However I have no experience with this type of device. As far as I know Lenovo does not offer anything similar.

 

Another option to consider is a 12VDC to 110/240VAC inverter together with the AC charger that came with the T580.

Cool! Thanks for the clarification. This must be a new product because I didn't see it a couple of months ago.
